Introduction

The challenge of increased food production to meet food security needs still persists 50 years after the start of the Green Revolution as population growth continues to increase in many developing countries. There appears to be no alternative but to increase agricultural productivity and the associated individual factor productivities (such as water, labor, nutrients, energy and capital) to meet the food demand by 2050 and to alleviate poverty and hunger. Thus, needs technological initiatives for further agricultural intensification. But already happening negative effect of crop production intensification on essential natural resources such as soil, water, biodiversity, and associated ecosystem services has forced agriculture stakeholders to search for novel initiatives that focus on sustainable production optimization rather than just intensification. Furthermore increased food supply is a necessity though not sufficient for eliminating hunger and poverty. What is important is who produces the food, has access to the technology and knowledge to produce it, and has the purchasing power to acquire it. Of the developing world’s 5.5 billion people, 3 billion live in rural areas – nearly half of humanity. Of these rural inhabitants, an estimated 2.5 billion are in households involved in agriculture, and 1.5 billion are in smallholder households (World Bank, 2008 and Herren, 2010). Poor farmers need low-cost and readily available technologies and practices to increase local food production and to raise their income. At the same time, land and water degradation is increasingly posing a threat to food security and the livelihoods of rural people who generally live on degradation-prone lands. There are several other key issues while relating the situation to Indian context.

Conservation agriculture is an approach to managing agroecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. Food and Agriculture Organisation of the United Nations (FAO) defines conservation agriculture as a farming system that promotes maintenance of a permanent soil cover, minimum soil disturbance (i.e., no tillage), and diversification of plant species.

Conservation agriculture (CA) defined as minimal soil disturbance (no-till) and permanent soil cover (mulch) combined with rotations is a recent agricultural management system that is gaining popularity in many parts of the world. Cultivation is defined by the Oxford English dictionary as “the tilling of land”, “the raising of a crop by tillage” or “to loosen or break up soil”. Other terms used in this dictionary include “improvement or increase in (soil) fertility”. All these definitions indicate that cultivation is synonymous with tillage or ploughing.

The other important definition that has been debated and defined in many papers is the word “sustainable”. The Oxford dictionary defines this term as “capable of being borne or endured, upheld, defended, maintainable”. Something that is sustained is “kept up without intermission or flagging, maintained over a long period”. This is an important concept in today’s agriculture since the human race will not want to compromise the ability of its future offspring to produce their food needs by damaging the natural resources used to feed the population today.

8.1 Introduction

Conservation agriculture (CA) is an approach to regenerative agriculture and land management practices based on three interlinked principles: (1) continuous minimum mechanical soil disturbance using no-tillage or reduced tillage based crop cultivation, (2) maintenance of permanent soil cover using crop residues and cover crops and (3) diversification of cropping system using economically, environmentally and socially adapted crop rotation including legume crops and cover crops coupled with other complementary agronomic management practices (FAO, 2014).

Introduction

The Indian agriculture is very complex and carrying out multi-functionalities of providing food, nutrition and ecological security besides employment and livelihood for over 700 million people. Indeed, India has made a marvelous achievement in attaining self-sufficiency in food grain production after the induction of Green Revolution which eventually resulted in maintaining all-time high buffer stock in warehouses of our country. Such rosy picture in production trends turned to be bleak in the past few years. There are various reasons behind this. Shrinking resources of prime lands, deforestation and accelerated erosion, deterioration of soil physical environment, increasing waterlogging and salinity in canal irrigated areas, declining water table in well-irrigated areas, poor management of rainwater, lower efficiency of inputs such as water, fertilizers and agrochemicals, rapid industrialization coupled with pollution and environmental degradation and hazards have aggravated the problem. At the same time, increase in atmospheric concentrations of greenhouse gasses (GHG), of which the most common is carbon dioxide (CO₂), is the primary cause of global warming and the Intergovernmental Panel on Climate change (IPCC) estimates that the current greenhouse gases (GHGs) concentrations are 30% more than the pre-industrial level. C is accumulating in the atmosphere at a rate of 3.5 Pg (Pg = 1015 g or billion tons) per annum, the largest proportion of which resulting from the burning of fossil fuels and the conversion of tropical forests to agricultural production. Under such circumstance, there is an imperative need to produce more from less arable land and water through meticulous management of basic agricultural resources such as soil, water and biological inputs.

Introduction

The green revolution is exemplified by too much adoption of high soil disturbance, modern varieties, energy exhaustive technologies, high amount of capital investment and simplification of farming systems (Meeus, 1993), resulting in uniform and featureless landscapes (Nassauer and Westmacott, 1987) in the most intensively farmed arable areas. In post-green revolution epoch, we had experienced a period of remarkable escalation in food productivity, despite rising land values and increasing land scarcity. Farmers from both developing and developed countries get exposed to several production constraints for achieving a sustainable, cost-effective and assured return from their field. Depending upon the circumstances and the scale of farm activities, farmers face varying degrees of climate risk, biotic invasion, and economic uncertainty. Thus, from the context of economical ambiguities, volatile food prices, social pressure to buffer ups and downs of agricultural production and achieving food security for ever growing population and curtailing poverty, farmers must be equipped with novel cultural practices to achieve a sustainable and assured cost-effective grain production. Research experiments throughout the globe found that the principal indicators for unsustainability of agricultural systems are: (1) intensive tillage induced decrement of soil organic matter (OM), structural degradation of soil, accelerated water and wind erosion, reduced water infiltration rates, surface sealing and crusting, soil compaction, (2) insufficient return of organic materials into soil, and (3) monocropping.

Introduction

Persistent use of conventional farming practices based on extensive tillage, especially when combined with removal or in-situ burning of crop residues, has magnified soil erosion losses and swiftly degraded soil resource base. One of the glaring examples for the aforementioned statement is the ‘Dust Bowl’ in the U.S during 1930s in Great plains, where 91 M ha of land was degraded by severe soil erosion (Hobbs, 2007).

One of the primary challenges of our time is to feed growing and more demanding world population with reduced external inputs and minimal environmental impacts (nature paper). Conservation Agriculture (CA) is a set of management practices for sustainable agricultural production without excessively disturbing the soils, while protecting it from the processes of soil degradation like erosion, compaction, aggregate breakdown, loss of organic matter, leaching of nutrients, and processes that are accentuating due to anthropogenic interactions in the presence of extremes of weather and management practices. The organic materials conserved through this practice are decomposed slowly, and much of materials are incorporated into the surface soil layer, thus reducing the liberation rate of carbon as CO₂ into the atmosphere. In the total balance, carbon is sequestered in the soil, and turns the soil into a net sink of carbon. So, CA enhance soil health by improving soil aggregation, reducing compaction through promotion of biological tillage, increasing surface soil organic matter and carbon content, and moderating soil temperature and weed suppression. CA reduces cost of cultivation, saves time, increases yield through timelier seeding/planting, reduces pest and diseases through stimulation of biological diversity, and reduces green house gas emissions.

Machinery development, refinement and adoption for a range of soil and cropping situations will be fundamental in any success to promote conservation agriculture practices. Agricultural machinery or tools, which support conservation agriculture generally refer to the cultivation systems with minimum or zero tillage and in-situ management of crop residues. Minimum tillage is aimed at reducing tillage to the minimum necessary that would facilitate favorable seedbed condition for satisfactory establishment of crop. Zero tillage is however an extreme form of minimum tillage. With the development of direct drilling machines, almost all research work was attempted to define the responses of direct-drilled seeds in relation to soil micro-environments. Different designs of direct drilling machines viz. zero till drill, no till plant drill, strip till drill, and rotary slit no till drill have been developed with controlled traffic measures for energy efficient and cost-effective seeding of crops without tillage. In this paper various issues, challenges and prospects of conservation agriculture in India has been discussed.

Green Revolution has increased food grain production by four fold since 1950–51 with the adoption of HYVs, intense input use, extensive tillage, burning of residues and irrigation. The intense cultivation has lead to degradation of natural resource such as soil, water, vegetation etc. In this context, globally conservation agriculture (CA) has opened a new paradigm as it has potential for higher resource use efficiency, water productivity and climate change mitigation through its key principles. Total area and percentage of total area under no tillage practised as part of conservation agriculture in different continents is given in Table 92.

Conservation agriculture is an approach to managing agroecosystems for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. Food and Agriculture Organisation of the United Nations defines conservation agriculture as a farming system that promotes maintenance of a permanent soil cover, minimum soil disturbance (i.e. no tillage), and diversification of plant species.

Conservation Agriculture Conservation agriculture is an approach to managing agro-ecosystems, for improved and sustained productivity, increased profits and food security while preserving and enhancing the resource base and the environment. It is a set of technologies, including minimum disturbance, permanent soil cover, diversified crop rotations, and integrated weed management (Reicosky and Saxena, 2007; Hobbs et al., 2008, Friedrich et al., 2012).

9.1 Introduction

According to FAO guideline, “Conservation Agriculture (CA) is an approach to managing agricultural ecosystems for enhanced and sustained productivity, improved returns, and food security while preserving and enhancing the resource base and the environment.”

The terms “conservation agriculture” (CA) and “resource-conserving technologies” (RCTs) are not synonyms, but sometimes both words are used for a similar meaning. Therefore, the practices which improve resource or input-use efficiency are termed as RCTs. RCT is a wider term than CA which is used for nitrogen-efficient varieties; fuel-, money-, and time-efficient techniques; and improvement in plot-level water productivity including CA.

Introduction

The development of insecticide resistant populations of insect-pests, evidence of resistance, resurgence and environmental concerns have led to increased research for the alternative strategies to pesticides for control of damaging pest populations. Classical biological control and the success in that area are important and provide background and encouragement for increased efforts in the manipulation of natural enemies. Methods for manipulation of natural enemies for the purpose of reducing herbivore populations and alleviating plant stress include conservation and augmentation, habitat management and genetic manipulation.

Virtually all pest populations are affected by natural enemies to some extent. In many cases, natural enemies are the primary regulating force of the pest populations. Natural controls include effects of natural enemies (predators, parasites, pathogens), other biotic (living) factors such as food availability and competition, and abiotic (non-living) factors such as weather and soil. In pest management, biological control usually refers to the action of parasites, predators or pathogens on a pest population which reduces its numbers below a level causing economic injury. Herbivorous insects and pathogens that attack pest weeds are also considered biocontrol agents. Biological control is a part of natural control and can apply to any type of organism, pest or not, and regardless of whether the biocontrol agent occurs naturally, is introduced by humans, or manipulated in any way. Biological control differs from chemical, cultural, and mechanical controls in that it requires maintenance of some level of food supply (e.g., pest) in order for the bio-control agent to survive and flourish. Therefore, biological control alone is not a means by which to obtain pest eradication.

Introduction

India ranks third in sheep population and accounts for 6.13 % of world population (FAO, 2009) with 71.56 million sheep to its record as of Livestock Census 2007 (DAHD, 2012). Out of 71.56 million sheep, 3.73 million are crossbred and 67.83 are indigenous. Sheep husbandry is backbone of rural economy in India. It is important as it helps in sustaining the livelihood of rural poor in difficult terrains characterized by sparse vegetation, marginal land and a high incidence of poverty. These breeds were developed following domestication and natural and artificial selection over the past 12,000 years.

India has vast animal genetic resources with a wide variety of indigenous farm animal breeds. These breeds have evolved over generations to adapt to specific agro-climatic and socio-economic needs of the people. Many number of these breeds are now subjected to fast genetic degradation and dilution because of unplanned and indiscriminate breeding and introduction of exotic germplasm.

Domestic animal diversity in developing countries is embedded in traditional farming and pastoral communities who manage their livestock according to their Indigenous Technological Knowledge (ITK) and in tune with local ecological constraints.

Threats

There are sixteen threat factors have been identified from Indian mangroves (Kathiresan 2010). However, habitat conversion for agriculture and aquaculture activities, environmental pollution by upstream anthropogenic activities, Climate change processes (e.g. sea level rise; increasing frequency of cylones, etc.) are the major threat factors for mangroves. Mangroves are able to cope up with short-term oscillations and long-term fluctuations of climatic conditions, but the consequences of global climate change, such as increased extreme events, will have unprecedented effects on biota and threaten the resilience and recovery potential of the ecosystems (Harris et al. 2018; Sippo et al. 2018). Despite conservation measures, the mangroves still experience an annual loss of 0.2-0.7% during 2000-2012 and they remain the most threatened ecosystem of the world (Hamilton and Casey 2016).

Collection and conservation of genetic resources in horticultural crops is very much essential in regions where local seed sources are still used in genetic enhancement and cultivar production. Domesticated crops grow well adapted to both tropical and temperate regions. In particular, if the crop is domesticated over centuries to be grown in different latitudes, the genetic diversity estimates are essential for a breeder to develop location specific cultivars. Genetic ulnerability, erosion and extinction of some wild progenitors and species has been altered, warranting the need for ex situ conservation measures. The material is conserved in various forms, ranging from botanical gardens, clonal and seed populations, vegetative methods, in vitro active repositories, pollen cryobanks and DNA banks. The objective, in genetic resource context, is to conserve for prolonged duration with minimal loss of viability and genetic diversity. Most ex situ conservation methods are technology dependent. Seed and pollen banks are dependent in refrigeration technology and cryogenic technology.
The conservation of plant genetic resources in ornamental species is generally driven by demand, focusing on preserving a wide range of genetic diversity. This diversity can include individual genes and coadapted gene complexes at the micro level, as well as entire genotypes, elite clones, and plant populationsat the macro level. The distribution of genetic diversity (GD) in plant species  is predominantly dependent on the reproductive mechanisms they adopt and the mode of inheritance of the characters targeted for collection. The main reasons for collection and conservation genetic resources of an ornamental species gene pool in a given ecosystem are:

Arecanut is an important traditional plantation crop of India and South-Eastern Asia. Also known as “betel nut”, the kernel is obtained from its fruit. It is mostly used by the people as masticatory and is an essential requisite during several religious, social and cultural functions of India. Arecanut has been widely used in East Africa, South-East Asia, and the Pacific Ocean islands, providing economic security for millions of people and for many sole means of livelihood in the Indian sub-continent. Arecanut is commercially cultivated in Bangladesh, China, India, Indonesia, Malaysia, Myanmar, Philippines, Sri Lanka, Thailand and Vietnam. Its current world production is 17.96 lakh tonnes from 12.26 lakh ha (FAO STAT, 2020).

Biodiversity is a matter of concern to everyone as most of the economic sectors depends on it e.g. agriculture depends on it for wild genetic resources and biological control, human health depends on nature for many pharmaceuticals, industry requires raw materials which come from the nature, tourism increasingly base its attraction on natural amenities linked to biodiversity, water resources require intact vegetation to protect watershed and prevent siltation, disaster prevention needs natural vegetation to help people to respond to drought and the lists goes on and on (Mc Neely, 2004). Each of these sectors needs to be reminded of its reliance on biodiversity and provided with opportunity to invest in insuring the continued survival of the biological basis of their prosperity. Thus biodiversity has emerged as an integral aspect of human life and hence undoubtedly one of the keystone of sustainable development. Biodiversity in arid lands are under severe threats due to habitat destruction (Manuder and Clubbe, 2002), invasion of species (O’Kennen et al., 1999) dilution of customary conservation practices, climate change (Given, 1994; WCMC, 1992), increasing human population, unsustainable exploitation of natural resources, grazing pressure etc.

India is floristically extremely rich with about 33 per cent of its botanical wealth (over 15,000 species of higher plants) being endemic. There are about 141 endemic genera distributed over 47 families (Nayar, 1980) the 4,900 endemic species, a large number are localised in the Himalayas (about 2,532 species), compared with the peninsular tract (1,788 species), and the Andaman and Nicobar Islands (185 species). Indian region is a major centre of domestication and diversity of crop plants (Zeven and de Wet, 1982; Arora, 1991). About 33 per cent of the cultivated plant species have theirorigin in this region (Damania, 2002). The Indian sub continent is a centre of domestication and diversification of several economically useful wild plant species comprising about 3,000 plants of edible value, 4,000 species having known reputed medicinal value, 700 plants of traditional and social significance, 500 fibre-yielding species, 400 fodder plants, 40 plants having insectivorous uses, 300 gum and dye yielding plants and 100 aromatic and essential oil-yielding species (Arora, 1991).

Introduction

Future agricultural production potential is in danger due to the existing cropping system, characterized by irresponsible chemical utilization, extensive tillage, monoculture, and soil health degradation. Consequently, a significant challenge for modern agriculture lies in ensuring adequate nourishment for the entire world’s population while also safeguarding the environment. The intensification of agricultural practices negatively impacts vital natural resources like soil, water, air, and biodiversity throughout various developmental stages. While the conventional cropping system have enhanced crop productivity, its consequences including land degradation, resource depletion, reduced organic matter insoil, draught, soil salinity, erosion, and climate change pose significant global threats (Tomar et al. 2014; Yadav et al. 2014; Mandal et al. 2020; Rani et al. 2021).

Chemical pest management is neither economically nor ecologically sustainable. As for example, the USA spent an estimated $11 billion on pesticides in 2008, applying more than 480 million pounds of these chemicals to its agricultural fields (Fernandez-Cornejo, et al, 2009). Despite this widespread use of pesticides, which cause severe harm to the mankind as well as the ecosystem, estimate suggest that 37% of the crop yield of the USA are lost due to pests (Pimentel, et al, 1992). This type of situation is witnessed all throughout the world. Under these circumstances, the natural enemies of agricultural pests may offer a sustainable solution to pest problems and the management they offer is worth of $13 billion per year in the USA (Losey and Vaughan, 2006). So, conservation of these biological control agents in the ecosystem is very much important for the sustainability as well as the health of the environment. Conservation and augmentation of natural enemies are among the main task in Conservation Biological Control (CBC).

Abstract
Aquatic ecosystems comprising freshwater, coastal, and marine environmentsarem vital for biodiversity, food security, and economic well-being, particularly in developing countries. Nevertheless, human activities increasingly threaten these ecosystems, including overfishing, pollution, habitat destruction and climate change. This chapter examines the conservation of these ecosystems through an ecosystem-based management (EBM) approach, which is crucial for enhancing ecosystem resilience and preserving biodiversity. EBM provides a holistic framework incorporating ecological, social, and economic dimensions, moving beyond traditional management strategies focusing on individual policies or species. By considering the entire socialecological system, EBM fosters sustainable fisheries and aquaculture while
ensuring the long-term availability of ecosystem services. The chapter underscores the significance of policy integration, stakeholder involvement, and innovative solutions to safeguard and sustain aquatic ecosystems amid persistent environmental challenges.

Abstract

Bhadawari is one of the recognized buffalo breeds of India and is famous for high milk fat content. The main breeding tract is Agra and Etawah in Uttar Pradesh and Bhind and Morena districts in Madhya   Pradesh. The tract was a part of the erstwhile Bhadawar estate from where the name of these animals originated. Bhadawari, the brown beauty of ravines and predominantly the only breed adapted to the harsh conditions of the ravines with undulating topography, thorny and scanty bushes, climatic stress and draught conditions. Breed is said to be resistant to many tropical bovine diseases and also known for eating less and producing more. Calf mortality is significantly lower than the other breeds of buffaloes. Male animals are good for agriculture work especially for ploughing in rice fields.

Introduction
The richness of a country can be measured by its biological diversity. It is essential to both human existence and financial security. The most basic concept of biodiversity is expressed by the diversity of creatures. Biodiversity is represented by the supplies of food, clothing, shelter, and medicines provided by plants; by the sources of food, assistance, wild life, and human resource efficiency provided by animals; and by the patterns of variation seen in the microbiological world. More than 20,000 kinds of ants, 3,000,000 species of beetles, 28,000 species of fish, and almost 20,000 species of orchids would be hard for the average person to believe.
Definitions
• The collection and interplay of genes, species, and ecological diversity in a specific location and time is known as biodiversity. Different genes, species, habitats, and their relative abundance are all included in the phrase biodiversity.
• The portion of nature known as biodiversity comprises the genetic variations between individuals of the same species as well as the variety and richness of all plant and animal species at various spatial dimensions, such as a region, a nation, and the entire planet.
• “The diversity of life, which encompasses ecosystem or community diversity, species diversity, and genetic diversity, and includes the entire range of variety and variability within and among living organisms and the ecological complexes in which they occur,” is another definition for it.

Ethnobotany deals with different aspects of man-plant relationship with special emphasis on ethnic community of a region, nay country or any geographical territory. This perhaps gives us a new dimension, orientation and objectives to make it complete with vivid information on people and their resource use pattern including science background behind scientific use. The new form of ethno-botany is now reformed and re-oriented as beta-ethnobotany. Earlier taxonomists, anthropologists and social workers have made their work on a wide field of man-plant relationship which was very loose in the sense that no specification or special focus was there which has its origin so called alpha-ethnobotany. Beta-ethnobotany deals with objective based oriented studies, divine, dynamic and quantitative ethno-botany with special emphasis to assessment of credibility of folk claims, ethno pharmacology, ethno-pharmacotherapy and ethno-medicine. Presently scientists estimated that out of over 5000 plants have been used in ethno-medicine much less than 1000 are utilized in herbal drug industry in different indigenous systems of medicine like ayurveda, homoeopathy, unani and siddha. A wide variation of use and conservation strategies on that medicine or the raw sources of these materials are available in the lower tract of Chotanagpur plateau in red lateritic part of West Bengal so called the ‘ rarh’ region. Tribal people like santal, kol, sabar, kheria, oraon, munda etc. inhabiting the rarh region use the medicine as ethno-medicine since time immemorial and conserve the plants and similar plant propagules in their home gardens and nearby sal (Shorea robusta) dominated forests for future generation. Wide application and conservation strategies of a large number of ethno-medicine and ethno-medicinal plants have been presented here with special emphasis on landscape conservation to make the ecosystem pristine rather than degraded in near future.

Introduction
India has vast animal genetic resources with a wide variety of indigenous farm animals including cattle. The cattle breeds have evolved over generations to adapt to the agro-climatic and socio-economic needs of the people. Domestic animal diversity is defined as the spectrum of genetic differences within each breed and across all breeds within each domestic animal species, together with the species differences; all of which are available for the sustainable intensification of food and agriculture production. The domestic animal diversity has evolved over millions of years through the processes of natural selection forming and stabilizing each of the species used in food and agriculture. Over the more recent millennia the interaction between environmental and human selection has led to the development of genetically distinct breeds. Selection processes, directed by both humans and the environment, together with the random sampling processes causing genetic populations to drift over generations, have accelerated the development of the diversity within species leading to the creation of distinct genetic differences amongst breeds.

India is the seventh largest country in the world and it is recognized as one of the 12-mega biodiversity centres of the world. It is well marked off from the rest of Asia by mountains and the sea, which gives the country a distinct geographical entity. Due to diverse agro-ecological regions and topographic conditions, India has rich repository of both flora and fauna. India has vast animal genetic resources with a wide variety of indigenous farm animals. Indigenous animal breeds are now 53 for cattle, 20 for buffalo, 39 for goat, 45 for sheep, 8 for horses & ponies, 9 for camel, 14 for pig, 3 for donkey, 3 for dog, 1 for yak, 20 for chicken, 3 for duck, and 1 for geese, besides many other non-descript and mixed populations. Livestock husbandry is an age-old important occupation for Indian farmers. The unique and rich animal biodiversity is extensively referred to in Indian scriptures.

Conservation Biology emerged as the scientific study of the nature and status of Earth’s biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction. Biodiversity itself has a wider meaning unifying and taking into account species, within species breeds/ varieties, ecosystem, genetic and molecular diversity.

Need for Conservation

The progenitor of modern-day chicken has been the Red Jungle Fowl and over the years breeds have been developed slowly for commercial purpose as layers and broilers. However we still have lot of indigenous birds which cannot be defined in either category.

Breeding capabilities Vs biodiversity erosion: Presently only about 3-4 poultry breeding companies provide meat stocks for farms around the world. A similar number of companies supply birds for commercial egg production. As a result modern animal industry now uses only a few breeds of any species. Of the many breeds once commonly seen on farms, many have declined sharply in numbers and others have disappeared almost completely.

Productivity Vs Conservation: On one hand, to increase productivity we want certain natural characters to be eliminated and on the other we talk of conserving the indigenous varieties, which sounds contradictory.

Abstract

Many people’s food and livelihood security depend on the sustained management of various biological resources that are important for food and agriculture. Agro biodiversity is the result of the interaction between the environment, genetic resources and management systems and practices used by culturally diverse peoples. The management of agro biodiversity by the indigenous communities is for a variety of reasons. The land use types, land use stages, aspect, soil fertility, availability of water and quality seed of crops etc. are essential variables which an indigenous farmer considers while cultivating a diversity of traditional landraces in the farm for food security. India is the largest producer of many kinds of millets, which are often referred as coarse cereals. However, realizing the nutrient richness of these grains they are now considered as nutria-cereals. Small millets, as a group includes several grain crops namely finger millet (ragi), proso millet, barnyard millet, italian millet, kodo millet and little millet. In the four decades since 1961, the area under millets declined by nearly 50% from about 18 million hectares to about 9 million hectares. During this time, production of millets declined from about 8.8 million tons to about 7.2 million tons; a decline of 18%. Tremendous decrease in area and production is directly or indirectly resulted in the loss of agro biodiversity of these crops as these crops are grown on marginal or rainfed areas without any fertilizers. Therefore, more emphasis should be given for maintaining bio diversity of these highly rich crops by increasing area under these minor millets and developing proper agro techniques for increasing its productivity.

Village Madangunj is situated on the bank of the Hatania Duaniya, a branch of the Hoogly River in Namkhana. The cyclone Aila unleashed its fury on the people residing on the islands in the Sundarbans and changed their lives forever. The Sundarban is the world’s largest mangrove forest and home to the Royal Bengal Tiger. The cyclone also affected the fish resources and livelihood of the villagers. Efforts were made to provide alternative sources of livelihood to the poor people of these villages.

Challenges and opportunities

We conducted field surveys to understand the status of small indigenous fish after cyclone Aila in the Sunderban region, particularly in Namkhana block, which was badly affected by the cyclone. Hundreds of people under various age groups ranging from 27 to 65 years old and involved in various occupations were interviewed personally to know about the present status of small indigenous fish after Aila. It was reported by 60% of the respondents that there is a significant reduction in the availability of small indigenous fish (SIF). To rejuvenate their stocks, it was decided to develop a conservation site, as a common seed bank for SIF. The SIF are self-recruiting species and can be cultured in various cultural systems like ponds, canals, wetlands, cages, etc. They can tolerate the adverse water quality cond

At the outset, I need to state that I am not a horticultural specialist and whatever horticulture knowledge have, is gained on the job and I am a plant genetic resources specialist with an interest in biodiversity and have worked across Asia. Today we will be mainly talking about tropical fruits and, in particular, tropical fruit tree genetic resources. If you look at tree fruits as a group, it includes a large number of species, unlike in field crops, e.g., rice, wheat, maize, etc., where just a few species are involved in each crop. Here we are talking about a group of species under each fruit tree. While talking about them, certain generalizations have to be made. Also, there are many unexploited species which are waiting to be discovered for human usage and exploitation, and there is hardly any genetic information available about them.

Aquatic ecosystems, particularly riverine habitats, are critical for global biodiversity, hosting over 30,000 described fish species, many of which are endemic and endangered. Freshwater fish are especially vulnerable to anthropogenic threats, including habitat degradation, pollution, invasive species, and climate change, leading to significant population declines. This chapter reviews conservation strategies aimed at protecting endangered river fish species. It emphasizes the importance of integrated management practices, including habitat restoration, establishment of aquatic protected areas, and stakeholder engagement in co-management initiatives. The significance of regulatory frameworks, effective policy ratification, and the role of public awareness and community participation in conservation efforts are highlighted. Additionally, the chapter explores innovative approaches such as ex-situ conservation, captive breeding programs, and sustainable harvesting practices as vital tools for fish population recovery. The challenges hindering effective conservation strategies are discussed, including limited taxonomic knowledge, insufficient understanding of fish ecology, and the need for holistic approaches that consider ecosystem interdependencies. Addressing these challenges is crucial for the sustainable management and conservation of freshwater fish populations and their ecosystems.

Introduction

Providing sufficient habitat and other food supplies to already-existing or naturally-occurring beneficial species is one of the most successful and long-lasting ways for reducing economic harm from pests. In contrast to monocultures or pesticide-treated fields, beneficial species such as predators, parasites, and pest-sicking "pathogens" are significantly more numerous in varied farms where pesticides are used less frequently.

Introduction

Agricultural productivity during past three decades resulted in depletion of natural resource base besides creating several environmental and ecological problems. In contrast the demand scenario features a growth rate in food requirements to meet the ever-increasing demand of the growing population. The total food grain demand of India by 2020 is estimated at 294 million tones as against the present 224 million tonnes (2010-11), which has to come from the almost static net cultivated area of about 142 million ha. This improvement in food grain production has to be achieved while dealing with the factors affecting the ecological balance and sustainability of Agricultural resources. Soil and water conservation is an important aspect, which needs very careful dealing with proper attention of the researchers and planners particularly in the context of agriculture of rainfed areas. As the water without soils is useless for crop cultivation, the soils without water nothing but desert. At least 20 % of total land is deserted and very difficult to use with another 20 % is sandy and poor in nutrient content subjected to severe soil erosion and excessive land degradation which causes fragile nature of eco-system and threatens food security of such areas. Soil erosion reduces productivity and cuts crop yield and causes at least 10 metric tons of topsoil loss per hectare per year. Now days, soil and water conservation is gaining paramount importance globally due to its obvious reasons. The main objective of the subject to protect soils against damage due to excessive runoff by natural, mechanical, cultural and agronomic measures to be adopted to bring a state of equilibrium between climate, soil, rainfall, slope and vegetation.

Objectives
• Provide a comprehensive understanding of consonant sounds in English.
• Familiarize learners with the International Phonetic Alphabet (IPA) symbols for consonant sounds.
• Enhance pronunciation skills through the correct articulation of consonant sounds.
• Enable learners to distinguish between voiced and voiceless consonants
• Equip learners with practical examples to apply phonetic knowledge in speaking and listening effectively.
Introduction
Consonant sounds are an integral part of spoken English, contributing significantly to the clarity and intelligibility of speech. Unlike vowel sounds, consonants are produced with a degree of constriction or closure in the vocal tract, which modifies the airflow. These sounds can be categorized based on various parameters, such as their place of articulation, manner of articulation, and whether they are voiced or voiceless.
The International Phonetic Alphabet (IPA) provides a standardized set of symbols to represent these sounds, ensuring a consistent approach to learning pronunciation. Understanding consonant sounds and their IPA symbols allows learners to decode and produce words accurately, improving their overall communication skills.

INTRODUCTION

Library Consortia is the sharing of resources among the libraries based on a number and utility over their respected areas. The resources that are shared in today’s consortia atmosphere are largely in electronic form such as electronic journals and databases. The aim of consortia is to accomplish what the members of the group cannot achieve individually, and its intention is sharing of resources, manpower and money, etc. It is regarded as a valuable strategy to increase the buying power and risk-sharing capacity of academic libraries over a short term. It is also a chance to maximize the opportunities for joint collection development and resource sharing over the long term. A consortium has the ability to share resources without forfeiting the individuality of member library. As a result, the end-users can collect the benefits of more resources than would be accessible through one library, while staff can adapt the system to meet their individual library’s needs. It can be a single agency with multiple locations around the world, all sharing one name, or the consortia members can retain their own name, but use the name of the consortia to recognize that they are the part of a larger, often worldwide, organization. It acts as director for the electronic resource sharing at the national, regional and local levels. The accessibility of IT-based electronic information products put forth portions of their budgetary allocation for either acquiring or accessing web-based online full-text search services, online databases shared services, on the one hand, permits flourishing consumption and desktop access to electronic resources at highly increasing users demands and growing cost of journals.

Biofertilizers can directly or indirectly influence the growth of plant. The direct influence can be through production of phytohormones or making the nutrients available to plants. The indirect effect can be through management of plant pathogens through biological control. Therefore, the purposeful introduction of biofertilizer inoculants to plant microbiome represents an environmentally sound option that holds a prominent position in order to reduce the dependency on agrochemicals (Adesemoye and Kloepper, 2009; Abhilash et al., 2016; Aloo, et al., 2019).

Microbes in soil can rarely exists as single cells and survive near the plant root canopy or in bulk soils or endophytes or even on plant surfaces (Lorito, 2006). The soil microflora occurs as complex members of microbiota (Hacquard, 2015). Microbial consortia (MC) are unique mixture of organisms which respond to the environment stress and adapt to stresses due to internal beneficial interactions among the microbial community. Ecosystem’s physiological functions by microflora is carried out by more than one microbial species with the functional diversity and succession among different microbial components. The microbial balance among the different microflora of a MC will consist of a continuous shift between actively growing cells and non-dividing cells of the microbial consortia. It has been reported that different microbial populations “talk” to each other by “quorum sensing” mechanism in a given environment by exchanging specific chemical signals (Thompson, 2015). Natural microbial consortia holds many specific properties like stability, functional diversity and perform complex functions. The natural consortia have generated an interest in manpulating synthetic consortia for the benefit of application (Minty, et al., 2013).

Constipation means difficult or infrequent passage of the feces. In some cases it is due to mechanical obstruction of the intestines, such as cancer, diverticulitis, or perhaps to some functional cause, such as an irritable colon discussed above. In most cases there is no actual obstruction.

Many elderly people suffer from constipation; probably they do not take sufficient fluid. They may think they are drinking enough, but careful observation may reveal that they are having only two or three glasses of liquid a day. For normal bowel habits, one should drink from six to eight glasses of fluid each day.

Sometimes constipation results from ignoring the normal call of nature. Many people suffering from constipation become dependent upon laxatives in early childhood. This is most unfortunate, for it means that the child may be dependent on drugs for the rest of his life. As far as possible do not use an enema on a child unless absolutely necessary. Laxatives and enemas are only for unusual conditions. Nature will provide for the normal needs of the body.

Key Points

• Constipation can be caused by a variety of clinical disorders or as a subsequent consequence.

• Rehydration and gentle lubrication of the GIT tract with oral paraffin or linseed oil will alleviate constipation caused by feed and water.

• Small animals, especially cats, are more prone to constipation.

• Common treatments for constipation include dietary changes, enemas, and mechanical removal under anesthesia.

Introduction

Constipation occurs when the ingesta moves slowly or not at all. It is a sign of several intestinal disorders. Although not all extra-gastrointestinal illnesses cause constipation, some do. A systemic illness is characterized by parasympathetic nervous system depression and constipation. Many diseases can lead to constipation as a complication. Chronic constipation in dogs leads to obstipation, which is characterized by drier, firmer, and more compact stools. Dogs cannot defecate and hence require medical intervention, such as surgery or manual feces evacuation. When the colon becomes irreversibly swollen and hypomotile (megacolon), surgery may be necessary. As a result, corrective actions for constipation should be implemented as soon as they are discovered. This will aid in a quick recovery from disease. The current chapter provides an overview of constipation in general and its management.

In India, self employment has been recognized as an essential force of development in rural areas. It has emerged as a strategy designed to improve the socio-economic life and mainly focuses on extending the benefits of development to the poorest in the rural areas improving their standard of living and self-realization. SHGs in India are integrating the low income segments with rest of the rural community by ensuring them a better contribution in a more equitable share in the benefit of developments. These Groups are not only speeding up economic growth, but also providing jobs and improving the quality of rural life towards self-reliance. Self-employment needs a very wide ranging and comprehensive set of performance, relevant to all aspects of rural economy and covering rural people including skilled, unskilled and landless labours and artisans of Rural India. The Rural Indians put their entrepreneurial skills in all the rural development performance  but their economic status has not improved to the expected level. They have much potential, despite they are ignorant of converting their skills into reality.

Village Panchayats existed in India long back, but the system has inherent weaknesses like the inability to be a people's government responsiveness to their needs. This was due to a variety of factors like a lack of financial resources, no regular elections and inadequate representation of the weaker sections (scheduled castes/ tribes and women) of the society. The Directive Principles of State Policy in the Constitution of India lays down in Article 40 that the government should facilitate the establishment and smooth functioning of the gram panchayats.

Introduction

Buffaloes thrive best in the areas of moderate rainfall as they require plenty of water for their daily bath. They live on coarser grass and even then are heavy yielders of milk. Buffalo species is thought to have originated in India. Indian buffaloes are the descendant of Bos arni found in north-eastern parts of India, especially in Assam & surrounding areas. There are two main types of buffaloes in India: River and Swamp types. However, both are called Bubalus bubalis. Most of the buffaloes in India are river types, though swamp varieties are also found in certain parts of the country, especially in eastern parts. Buffalo is our main milch producing species, that’s why the contribution of buffaloes to the total milk production is larger than that of cattle. India is the home tract of some of the best buffalo breeds.

Commercial pig farming in India is one of the best and profitable business ideas for the Indian people. There are several highly meat producing pig breeds available around the globes. Some of those are very suitable for commercial meat production according to the weather and climate of India. A few years back, pig farming had a bad image in the society, but at present at scenario has changed tremendously and commercial pig farming in India is no more restricted to lower class people. Now peoples are conscious about the economic value of pigs like other domestic livestock animals; and higher cast, educated people also started commercial pig farming business in a modern and scientific manner.

Among all domestic animals, pigs are the most prolific animal, giving 6-12 piglets in every litter and they are fast growing, attain a body weight of about 68 kg in about 6-8 months time, when they can slaughter. Pig has shortest generation interval among meat producing livestock. Pig products such as pork, bacon, ham, sausages, lord (pig fat) are increasingly in demand both for local consumption and for export. Pig skin used for the manufacture of light leather goods. Pig manure contains Nitrogen: 0.70%, Phosphorus: 0.60% and Potassium: 0.70%. Swine has superior feed conversion power (1: 3-3.5). Swine store fat rapidly. Pigs are prolific and bring quick return. A unit of 10 sows and 1 boar will produce about 160 piglets during the first year. Gilts may be bred between the ages of about 8-9 months furrowing when approximately 13 months old. Piggery enterprise requires moderate investment. Pig has highest dressing percentage (Pig: 65-80%) as compare to cattle (50-60%) and lamb and sheep (45-55%). Pork is the most nutritious meat. Pig is extremely sensitive to unfavorable ration and to careless management. Pigs are very susceptible to numerous diseases and parasites. Sow should required skilled attendants at the time of furrowing.

Introduction

Horses are adapted for run to quickly escape from predator. They possess an excellent sense of balance and strong fight or flight response. Related to this need to flee from predator in the wild is an extraordinary trait. Horses are able to sleep both ways i.e. standing up and lying down. Horses and humans interact in a wide variety of sport competitions and non-competitive recreational pursuit, as well as in working activities such as police work, agricultural, entertainment and therapy. Horses were historically used in warfare, from which a wide variety of riding and driving techniques developed using many different styles of equipments and methods of control. Many products are derived from horses, including meat, milk, hide, hair, bones, and pharmaceuticals extracted from the urine of pregnant mares.

Unit of measurement of Horse is Hand (1 Hand= 4 inch). NRC equine situated at Hissar, Haryana. Mares may give milk up to 18 litres daily. Famous donkey sanctuary situated at Devon in U.K. In India, there are 6 well known distinct breed of horses i.e. Marwari (Origin: Rajasthan), Kathiawari (Origin: Gujrat), Spiti (Origin: Tibet and Himachal Pradesh), Zankari (Origin: Jammu and Kashmir), Manipuri (Origin: Manipur and Assam) and Bhutia (Origin: Sikkim and Darjeeling). Besides these, FAO also recognized 3 more breeds: i.e. Chummarti (Origin: Tibet), Deccani, Sikang.

Introduction

Mithun is to be originated before more than 3000 years ago. Mithuns are found over a large area of southest Asia. This animal’s natural habitat is in the forests of highlands. In addition to meat production, Mithuns are used for sacrificial purposes and also for barter trade. Even today, Mithun is used as a holy sacrificial animal to appease the god by the tribe people. Mithun is a unique bovine species which are situated at limited geographical distribution. It is mainly found in the tropical rain forests of North Eastern hilly states of Arunachal Pradesh, Nagaland, Manipur and Mizoram of India. Mithun is also known as “Cattle of Mountain”. In Indian subcontinents, Mithun is also known as “Gayal” (Bos frontalis). In Myanmar and Bhutan, it is called Mithun, whereas in China, it is called Dulong cattle.

Mithun is a magnificent massive bovine and is presently reared under free range condition in the hill forests at an altitude of 1000 to 3000 m above mean sea level. Mithun plays an important role in the socio-economic and cultural life of the local tribal population. Presently, this animal is mainly reared for meat, which is considered to be more tender and superior over the meat of any other species. Although, Mithun produce less quantity of milk and can be used for preparation of various milk products. Leather obtained from this species has been found to be superior to cattle.

The massive unique beautiful animal is anatomically a physiologically well adapted to high altitude. Mithun is a social animal; they establish small groups usually containing an adult male and several female and juveniles. It is a potential source of delicious meat, and it can also be used for improvement of local, native cattle breeds. Mithun hide has almost three times the size and thickness that of native cattle.

Abstract

The present study was undertaken to analyse factors contributing to participation of rural women in Self Help Groups (SHGs), constraints faced by them and to elicit their opinion to strengthen the role of SHGs. The finding has revealed that, majority of the respondents has suggested that they should be provided with loans and the rate of interest on loans should be less.  Further, they also suggested that instead of existing loan structure from the bank and saving amount within the group must be increased which can be invested on other activities. It was also reasoned that the provision of low interest loan from the banks and purchase of raw materials at cheaper rate can improve the financial status of farm women.

Introduction

Women entrepreneurship in economic development of any nation has been recognised for its significant contribution. The women folk can be considered as backbone of any nation. Now time has come for women empowerment. In rural Odisha, women not only play an important role for agricultural development but also plays significant role in allied agricultural sector such as dairy, fishery, poultry, mushroom production etc. In Indian condition dairy has been considered as “Rural Banking” as it is practiced mostly by majority of the marginal, small and landless farm families for their sustenance and livelihood. The role of rural women for animal husbandry is of paramount importance. In this sector they are managers as well as decision makers. Women do more than 80% dairy operation like cleaning, feeding, milking, marketing of milk and milk products. The state and central government initiate several scheme, programmes and projects for empowerment of women through various micro enterprises including dairy. Against this background a study was undertaken to identify the constraint faced by women entrepreneur in dairy sector in Khordha district of Odisha.

Introduction

The total population of India according to recent estimates in 2015 is 1.28 billion (Anonymous, 2011). The population in the age-group of 15-34 years in India increased from 353 million in 2001 to 430 million in 2011. More than 50 per cent of India’s current population is below the age of 25 years old and over 65 per cent below the age of 35 years old.

The total population of Chhattisgarh State is 25,545,198 of which male and female are 12,832,895 and 12,712,303. Sex ratio is 991 i.e. for each 1000 male, which is above national average of 940. Literacy rate in Chhattisgarh has seen upward trend and is 71.04 per cent (Anonymous, 2011). Out of total population of Chhattisgarh 23.24 per cent people live in urban regions and 76.76 per cent people live in the villages of rural areas.

Women are the most potent segment of the population of a country. The women of today are the hopes of tomorrow. They are the back bone of the country. The socioeconomic development and prosperity of rural areas depends to a considerable extent, on the type of women living in rural areas, because the rural women have abilities to orient themselves to go along the main stream of the development process. They reflect the national potentiality and represent the life blood of a nation. Development of women determines the development of community and country as a whole. So, the future of the country lies in their hands, what they will become, what role they will play in a democratic society and what they will do, will be dependent to a greater extent on the period between their childhood to adulthood.
